I gues it got snowed in. Uniaud seems to have issue's with issue's with dealing with audio buffers. This bug does not only occur with the versions of which I reported this around 9 months ago. The problems are still there with the latest build from the Netlabs FTP server. Its also chipset independent and has been tested on about 5 machines. This audio buffer problems can result in hanging applications that can not be killed (waiting for an audio buffer event!?), audio device being blocked or even in some rare cases a system trap. Vladest I have provided you with version of Quickmotion. Its licensed and included with each install of eComstation 1.2 or higher. I can send it to you privately again. Old email I send: >With this same MPG file (bloopersextra.MPG) the audio playback results >in hanging desktop (can still do a C-A-D). >So something is chocking on the audio buffers !? I did get a TRAP once >when playing MPEG files with IBM's open MPG. Can you pinpoint where this code >crashed ? Its not an easy bug to reproduce with UNIAUD.
